Without knowing what you meant by "fried", I will suggest that whatever you changed, you change it back to whatever last worked. If you changed the tuning, hopefully you can put the tune back the way it was.

If the PCM is toast, you will need a new one, plus the dealer to program that new one. No, you can't do it yourself unless you have a Tech 2. I still have to wonder how it came to be in that condition? If its just a matter of the program wiped out, the dealer "may" be able to re-flash it back to factory specs. But, if the circuits are litterally burned, then there must be a cause and tuning isn't it. You need to identify the cause BEFORE putting in a new one otherwise you will end up with another paper weight.

I think that HP tuner has a PCM recovery mode... so it should have been able to fix whatever happened during the flash to "fry" your computer. Have you tried reflashing to see if it can be corrected? If your tuner was the one flashing your computer when it was "fried", I'd be expecting him to help you to resolve this. Now if the problem is electrical and nothing to do with the tuner, I guess you're on your own. Sorry to hear of your troubles - good luck fixing it - Bruce

I suspect that he can no longer communicate with the PCM, which means he needs a new one.
It is not clear what the sequence of events were that caused this, so it's kind of hard to help...

Yeah, if he or whomever was writing to it and the system went down, assuming the comm subroutine being written too at the time, its a brick now. I truly don't know if the dealer can still flash it or not, but it sounds like dealer time for him.

The PCM and BCM share a secret internal password between them. A Tech 2 will be needed regardless of the source of the new PCM. The two have to be sinked up to talk to each other again for security reasons. There is a procedure in the manual that will allow you to re-sink the security manually.

Back to the PCM, if it has corrosion on it, then you should be looking at the battery and leakage from it onto the wiring harnesses around the PCM. Many have had major issues there. You will need to jack the car, remove the right front tire and pull off the wheel housing so you can get to it.
Can you pull the codes?
